Show syntax lexer name in file view/blame ()
Show which Chroma Lexer is used to highlight the file in the file
header. It's useful for development to see what was detected, and I
think it's not bad info to have for the user:

Also, I improved the way this header overflows on small screens:

Upgrade chroma to v2.3.0 ()
The behaviour of `PreventSurroundingPre` has changed in
https://github.com/alecthomas/chroma/pull/618 so that apparently it now
causes line wrapper tags to be no longer emitted, but we need some form
of indication to split the HTML into lines, so I did what
https://github.com/yuin/goldmark-highlighting/pull/33 did and added the
`nopWrapper`.

Maybe there are more elegant solutions but for some reason, just
splitting the HTML string on `\n` did not work.

Improve code diff highlight, fix incorrect rendered diff result ()
Use Unicode placeholders to replace HTML tags and HTML entities first, then do diff, then recover the HTML tags and HTML entities. Now the code diff with highlight has stable behavior, and won't emit broken tags.

Fix copy/paste of empty lines ()
* Fix copy/paste of empty newlines again

Fixes: https://github.com/go-gitea/gitea/issues/19331
Regressed by: https://github.com/go-gitea/gitea/pull/18270

Needed to do another newline addition to the Chroma output HTML to get
copy/paste work again. The previous replacement conditions are probably
obsolete, but as I'm not 100% sure, I opted to keep them.

Specifically, the Chroma HTML change mentioned in
https://github.com/go-gitea/gitea/pull/18270#issuecomment-1013350246
broke our previous newline replacement for such empty lines.

Also included are a few changes to make the test more pleasant to work
with.

* run go mod tidy

* add util.Dedent

* copy in the code

Ensure syntax highlighting is the same inside diffs ()
Make sure to end up with the same syntax highlighting inside various sections of diffs by processing the code first before detecting specific changes between the lines. Also try and make sure that when highlighting individual lines in a diff that it is tokenized the same as it would be when part of an entire file with more context.

Also while looking at this I saw a small display issue for blame view. I think  was merged into original PR through an update branch before  was merged and made one of the css ruules not apply anymore.

Remove newline when highlighting random chunks of code ()
* Remove newline when highlighting random chunks of code

Somewhere when tokenizing a newline gets added to code formatted by chroma. This breaks the case of 'added-code' inside of an 'added-line' in a diff. Just remove any newline when processing chunks of code since we don't need it.

Fixes 

* don't process empty lines

* This is the proper way to fix this by telling chroma not to add the newline in the first place
